The aim of reporting this unusual case is to identify mature glial tissue deposits in the peritoneum in a case of immature teratoma of right ovary; a diagnostic challenge for a neophyte in pathology. We report a case of a 60 year old female with complaints of vague abdominal pain for 1 year. On ultrasonographic examination, the right ovary was found to be enlarged and was followed by salpingo-oophorectomy. Intra-operatively, small papillary excrescences were noticed in the omentum so it was also sent for histopathological examination. Paraffin sections showed features of Grade II immature teratoma and immunohistochemistry using GFAP was done for the peritoneal deposits. Immature teratomas accounts for about 20% of all the ovarian tumors and occurs predominantly in children and young women averaging age of 20 years. It is rare phenomenon in postmenopausal women thus making our case a diagnostic challenge. Gliomatosis peritonei was confirmed in the omentum, a rare finding about 88 cases have been reported so far worldwide. The first case from India was reported in 1981 by Joshi et al, henceforth, only four cases have been reported.
Key words: Gliomatosis Peritonei (GP), Glial Fibrillary Acidic Protein (GFAP), Immature Teratoma.
